FREDERIO O. GILFILLAN, OF EBENEZER, NEW YORK.

GAS-BURNER.

SPECIFICATION forming part of Letters Fetter It No. 647,183, dated April10, 1900. Application filed May 17, 1899. Serial No. 717,118. (Nomodel.)

To aZZ whom, it may concern.-

Be it known that I, FREDERIC O. GILFIL- LAN, a citizen of the UnitedStates, residing at Ebenezer, in the county of Erie and State of NewYork, have invented new and useful Improvements in Gas-Burners, of whichthe following is a specification.

This invention relates to a burner for gasan elevation showing two ofmyimproved gas:

burners arranged on opposite sides of a center burner. Fig. 2 is avertical section of my improved burner. Fig. 3 is a bottom plan view ofthe cover of the burner. Fig. 4 is a top plan view of the burner withthe cover removed.

Like letters of reference refer tolike parts in the several figures.

A represents a main or center gas-burner of any usual or ordinaryconstruction, whereby the water-front or the bake-oven of the stove isheated and which is provided with a gas-supply pipe at and an air-mixera.

B B represent two of my improved gasburners, which are arranged onopposite sides of the main or center burner A, so as to heat the lids ofthe stove or a vessel placed over the lid-openings. Each of the burnersB consists, essentially, of a cylindrical body or head 0, having abottom 0 and an open top, and a circular cover or disk (1, which isarranged on top of the body. The body of the burner is mounted on theupper end of a hollow fuelsupply pipe or standard E, which latter isconnected at its lower end with a gas-supply pipe e and an air-mixer e.The inner side of the body is provided with an annular series or row ofinclines or sloping faces f and a corresponding number of abrupt faces feach of which is arranged between the bottom of one incline and the topof the adjacent incline. The cover is provided with an annular row ofopenings g, which is arranged outside or out of line with the bore ofthe fuel-supply pipe E. The under side of the cover is provided with anumber of depending lugs or toes h, each of which engages with one ofthe inclines of the body. The cover is also pro- -vided with a concavedepression or deflectinclines toward the top thereof the cover is liftedfrom the body and an annular space is formed between the edge of thebody and the marginal portion of the cover, as represented in the burnerB on the right side of the center burner, Fig. 1 and also Fig. 2. Inthis position of the cover the fuel issuing from the upper end of thesupply-pipe strikes the concave face on the under side of the cover andis thereby deflected outwardly through the space between the cover andbody and produces a large spreading flame around the burner. Byarranging the openings h of the cover outside of the bore of thefuel=supply .pipe the gas issuing from the latter does not pass outthrough these openings, but strikes the concave face h of the cover. Asthe gas strikes the face 72/ it rebounds and is deflected sidewise pastthe cover openings and out through the space between the cover and body.Practically all of the gas passes through this space, and only aninconsiderable amount of gas, if any, passes through the cover-openings,thereby producing a burner of great heating capacity when the cover israised. By engaging the lugs of the cover with higher or lower portionsof the inclines the width of the space between the edge of the cover andthe edge of the body can be regulated so as to vary the size of theflame. The abrupt faces f on the body are engaged by the depending lugsof the cover and arrest the turning movement of the cover in thedirection for closing the space between thecover and body, the partsbeing so con structed that this movement of the cover is arrested whenthe cover rests on the body. For convenience in turning the cover thelatter is provided on its upper side with a shifting pin or lug t. Itwill be seen that this burner is composed of but two parts and, iscapable of producinga narrow or a wide flame by a partial turn of thecover, thus simplifying the construction and cost of manufacturing thesame and at the same time retaining r all the desirable features of amore complicated gas-burner.

K represents a supporting collar which surrounds each of the hollowstandards between its burner and its air-mixer. k is a horizontalsupporting-rod which is adj ustably secured at its inner end in a lug Zon the center burner by a set-screw Z and which has an externalscrew-thread at its outer end. The outer screw-threaded end of thesupportingrod engages with a screw-threaded openingin thesupportingcollar and bears against the side of the hollow standardin thecollar. By loosening the supporting-rod in the collar the standard canbe raised or lowered for adjusting the burner in the stove, and upontightening the rod against the standard the burner is held in position.By this means of sup porting the burner the horizontal rod serves thedouble purpose of supporting the burner and also as a means of adjustingthe same.

I claim as my invention 1. In a gas-burner, the combination with ahollow body provided in its bottom with a fuel-supply opening, of acover which is adjustable toward and from the body and which is providedwith a concave deflecting-face arranged opposite the fuel-supply openingand with a number of openings which are ar the cover, or the cover maybe separated from the body and form a space between the cover and bodythrough which the gas passes laterally, substantially as set forth.

3. In a gas-burner, the combination with a hollow body connected with agas-supply and provided with an annular series of inclines, of a coverarranged over the'bodyand provided with openings and with'lugs engagingwith said inclines, whereby upon turning said cover so that its lugsengage with the bottom of the inclines the cover engages with the bodyand permits gas to pass only through the openings of the cover whileupon turning the cover so that its lugs ride upon the inclines' thecover is moved away from the body and forms a space between the coverand body through which gas passes laterally, substantially as set forth.

Witness my hand this 6th day of May, 1899.
